Answer:
79°
Step-by-step explanation:
Assuming the diagram need to complete the question is the same as the one attached below,
From the diagram,
∠A+∠B+∠C = 180 (sum of the angles in a triangle is 180)..................... Equation 1
Given: ∠A = 22° (Vertically opposite angles are equal), ∠B = x, ∠C = x
Substitute these values into equation 1
22+x+x = 180
2x+22 = 180
2x = 180-22
2x = 158
x = 158/2
x = 79°
Hence the value of x is 79°
